Soybean and beanpaste have been used as ore of the important food in Korea. Beanpaste is made from soybean(seed of Glycine max $M_{ERRIL}$, Leguminosae) by traditional fermentation. It was expected that the secondary metabolites might be formed by the action of some microorganisms or enzymes on the constituents primarily contained in soybean during manufacturing or storage of beanpaste. A systematic investigation on the chemical constituents was carried out. As a result, sterol glycoside named daucosterin, lipo-daucosterin have been isolated from the lipid fraction soybean and their structures elucidated basis of chemical and physicochemical evidences. A ratio of composition of the lipid constituents in soybean and beanpaste were estimated.
